Most of the logic gates use two binary inputs and generates a single output like 1 or 0. These are the basic building blocks in the digital ICs (integrated circuits). The basic logic gates are used to perform fundamental logical functions. If you don’t know about the logic gates and their truth tables and need guidance on them, please go through the following infographic that gives an overview of logic gates with their symbols and truth tables. Every possible combination depends on the number of inputs. When drawing a truth table, the binary values 0 and 1 are used. All the logic gates have two inputs except the NOT gate, which has only one input. The truth table is used to show the logic gate function. The basic logic gates are classified into seven types: AND gate, OR gate, XOR gate, NAND gate, NOR gate, XNOR gate, and NOT gate.
Basic Logic Gates Operation What are the 7 Basic Logic Gates?
These logic gates with their logic gate symbols and truth tables are explained below. The basic logic gates are categorized into seven: AND, OR, XOR, NAND, NOR, XNOR, and NOT. Logic gates are used in microprocessors, microcontrollers, embedded system applications, and in electronic and electrical project circuits. But, in practice, basic logic gates are built using CMOS technology, FETS, and MOSFET(Metal Oxide Semiconductor FET)s. These gates are implemented using electronic switches like transistors, diodes. The relationship between the i/p and the o/p is based on a certain logic. A logic gate is a basic building block of a digital circuit that has two inputs and one output.
